Senior Full Stack Software Engineer with 9+ years building scalable, production-grade systems across fintech and e-commerce. Backend-leaning, cloud-native, and precision-driven.
I'm Abel Mhlanga, a Senior Full Stack Software Engineer based in South Africa with over 9 years of experience designing and delivering robust backend and full-stack systems.
My work spans fintech and e-commerce environments — high-stakes domains where performance, reliability, and security are non-negotiable. I specialise in microservices architecture, cloud-native infrastructure on AWS, and API-first development.
I approach every system with a bias toward clean architecture, testability, and long-term maintainability. I'm comfortable operating across the full stack, but my deepest expertise lives on the backend — where complexity is real and trade-offs matter most.
Architecting scalable microservices on AWS, leading backend API design with Node.js and TypeScript, and implementing CI/CD pipelines that reduce deployment friction. Driving system reliability across high-traffic payment flows.
Built and maintained GraphQL APIs, React frontends, and PostgreSQL-backed data models. Delivered features end-to-end across the stack while improving test coverage and system observability.
Developed RESTful APIs, database schemas, and server-side logic across multiple client projects. Introduced Docker-based development environments to standardise team workflows.
Open to senior full stack Python and backend roles, remote or UK-hours positions. Always happy to discuss interesting engineering challenges.
